SAMUEL H. LEWIS, OF NEV YORK, N.

.Specification forming part or" Letters Patent No. 41,939, dated January 26,'1347.

[0 MZ whom it may concern,.-

Be it known that I, SAMUEL H. Lnwrs, of the city, county, and State Of New York, have invented a new and useful Improvement in the Faucet and Filter Combined for Purifying Water from Aqueducts, Reservoirs, or drants; and I do hereby declare that the fol lowing is a full and exact description thereof, reference `being had to the annexed drawings, of which- Figure l is a perspective view, and Fig. 2 is a sectional view, ofthe internal construction and arrangement of the water-channels and reversible filter.7

In Fig. 1, A is the filter-chamber; B, the

, pipe through which the water is received into the chamber; C,` the pipe by which it is discharged, and D the key or faucetvvalve with the handle E, whereby the position Of the faucet-key is Occasionally changed.

In Fig. 2, A B is the water-pipe, passing through the center Of the filter-chamber, the

induction of the water being at A and the eduction at B. A faucet valve, plug, or key, C D, is nicely fitted 'to a socket which passes through the center of the filter and chamber, intersecting the water-pipe at right angles.

The shaded parts of the drawings in this iig ure represent the orifices and cavities in the apparatus. E E and F F are two metallic cir` cular plates or disks, which extend over thev area of the chamber, and between these two plates is inclosed and compressed a quantity of cloth, felt, porous stone, or other ltering material, which prevents the passage Of the water from one section of the chamber to the other, as from G to H, except through the pores of the filter. The faucetkey has no orice through it, but has a cavity or groove in each side thereof, whereby communications are` opened between the water-pipe and the sections of the lter-chamber through orifices in the sides of the key-socket. Thus when the key is in the position represented in the iigure, a communication is opened from A to G and from H to B; but when the position of the key is reversed, the Water will first enter the section H, and, passing through the filter to G,will pass Off at B. By thus changing the direction of the water through the lter the latter becomes cleansed from whatever sediment may have thereon accumulated. When the position of the key varies ninety degrees either way from the position represented in Fig. 2, the Water-channels are entirely closed. The filter-chamber Or external casing may be made of glass or any of the metals.

Vhat I claim as my invention, and desire to secure by Letters Patent, is

The construction of the faucet plug or key with water-channels in its sides correspondtng with the or'ice in the water-pipe and with those in the sides of the socket,whereby the direction of the flowing water is occasionally reversed and made to pass through the filter in opposite directions, also the combination of the faucet key and socket with the filter and f1lter-chambers, as herein described.
